Race was self-reported by participants from a list created by National Health Interview Survey researchers (African American, Alaska Native, American Indian, Asian, Black, Native Hawaiian, Pacific Islander, White, and other). Participants could select more than 1 race and self-reported whether they were of Hispanic or Latino origin. We classified participants as being Hispanic, non-Hispanic Black, non-Hispanic White, or other. Estimates for participants from other racial and ethnic groups were not included because of small sample size. The other group included participants who were Alaska Native, American Indian, Asian, Native Hawaiian, Pacific Islander, multiracial, or other race. Race and ethnicity were assessed to characterize differences in the burden of type 1 diabetes.
